Tlctl'lwhom it A"mfg concern:

Beit-known that I, JERvIs R. HARBECK, a citizen ofthe United' States, and residing at Detroit, in the county of Waynel and State of`M'ichigan, have invented a new and use- `iult Tube-Drying r paratus, of' which the following ,is a speci cation` My invention relates to means for drying tubes formed from fibrous material by 4winding the same on al mandrel, and the object of this .improvement is lto providey a simple and effective. drying apparatus for tubes, wherein means are rovlded to receive each individual tube as 1t is formed, carrying it away from the machine, and then deposit it inany desired receptacle.

My invent-ion consists in an endless conveyer belt or chain having outwardly projecting pins properly spaced, which pins are adapted to recelve the tubes, the apparatus beingso installed that at each operation of the tube machine, a carrying pin willv be in such position to receive each completed tube at its discharge from the machine.

-ln the accompanying drawings, Figure 1 is an elevation of my tube drying apparatus. Fig-.2 is a pla-n of a portion of the tube Inachine and the driving mechanism. Fig. 3 is a detail of the driving mechanism. Fig. 4 is a. detail of the' conveyor chain. Fig. 5

,is a detail of the auxiliary tube pushing and 80,.in which is revoluble a hollow shaft 79, upon the end of which is secured the mandrel 81 upon which the tubes are wound. Slidable on this mandrel and shaft lis a sleeve 150 provided with a circumferential groove 151, in which groove the fork 152 engages. Slidable in the bearings 78 and 80 is a rod 153 one end of which carries the fork` 152 and which also is provided with a collar 154. A lever 155 is carried by the table and .its upper end fits in a groove in this collar 154. A pin 157 projecting downward from this lever is adapted to be en aged by the cams 158 and 159 secured to t e drum each tube formed on the machine, and therefore at each' revolution of the drum a tube is ejected from the machine by sliding it off the mandrel 81 through the action of the sleeve 1.50 and thel fork. 152. Secured to the bed 1 is an inclined base 95, on which are mounted the side plates 96. Further descritionv will be found in the patent above cite The main driving shaft 56 of the tube machine' is extended andgiven an additional bearing 2, and it has mounted on its end a pinion 3 which meshes with the gear -l mounted on the shaft 5. Thisyshaft is revoluble in the bearings 6 secured to the lower side of the table 1. A bracket 7 pro- .jectingi'rom the table carries a shaft 8 at its outer end on which are revoluble the Isprocket wheels 9 and 10, which Wheels are secured together. Sprocket chain 11 connet-,ts the wheel 9 to the sprocket wheel 12 on the shaft 5.

Secured to the ceiling or any other convenient support is a bracket 13 which carries a shaft 1.4. upon which is journaled a sprocket wheel 15. A sprocket chain comprising plain links 16 and carrier links 17 `passes around the sprocket wheels and 15.

The carrier links are each provided with a projecting pin 18 which is adapted to receive the tube.

As explained in the patent cited, a frame is mounted on the bed 1, and comprises the side plates 96, which form the bearings for the feed rolls. Secured to one of these side plates is a bracket 20 provided with an aperture `in which the rod 2l is slidable. Secured to the bed 1 is an upright rod or frame 22 which has an aperture at its upper end for the rod 21. The rod carries a plate 23 at its outer end and a second plate 24 at its inner' end. A spring 25 between the bracket 2O and the pin 26 normally holds the rod in 'its retracted position. A nger 27 secured to the fork 152 is adapted to operate this rod.

The operation of this mechanism is as follows. The proportions of the pinion 3, the gearing 4 and the lsprocket wheels 9, 10, and 12 are such that the conveyor chain will travel the distance between two adjacent pins `18 at each forming of the tube. The parts are so positioned that a pin 18 will be o posite the end of the 57. This drum makes one lrevolution for mandrel 81 as a tu e A is being pushed o' 110 the mandrel through the action of the sleeve 150. The distance between the adjacent pins 18 is such that at the time a tube A is slipped oil the mandrel, the pin Which carries the lube made just before, will be above the lop oi the plate 23. As it is undesirable (hat the action of the sleeve 150 should be greater than absolutely necessary, the distance the just finished tube is slipped onto a pin I8 is less than is desirable. The rod 21 is therefore mounted in the bracket 2() and 'Frame 22 so that the plate 23 Will 'give the tubo an additional movement, pushing it entirely onto the pin 18, Which is accomplished by the linger 27 contacting Withthe plate 24 on. the end of the rod 21. After the tubes have traveled up around the Wheel l5 and then-back down to the Wheel l0 they will have become sufficiently dry and slip off into the receptacle 30.

lHaving noW explained my improvements what I claim as my invention and desire to secure by Letters Patent is In a tube drying apparatus for tube machines, the combination of a conveyer chain, wheels therefor and mechanism to drive the wheels, certain of the links of the chain being provided with tube engaging pins so constructed and arrangedas to receive thev tubes as they are formed, means on the tube machine to discharge the tubes therefrom and place them on the pins,.and inde endent mechanism actuated by the tube disc arging means of the tube machine, for properly positioning the tubes on the pins.

In testimony whereof, l have signed this specification in the presence of two subscribing Witnesses.
